Abstract: In the title mol­ecule, C17H12F2O3, the dihedral angle between the benzene rings is 8.6 (2)°. In the crystal, two pairs of O-H...O hydrogen bonds connect the mol­ecules into inversion dimers. In addition, weak C-H...F hydrogen bonds link the dimers into a two-dimensional network parallel to (10-4). The carbonyl O atom is an acceptor for two weak intra­molecular hydrogen bonds.
